I understand, but it’s a so common event when someone makes linguistic mistakes while speaking in English (I’m not an exception myself), that it isn’t really worth mentioning it, I think. It’s a world language, after all.

imo it helps for various reasons but the topic isn’t a big deal worth making a case for. i think it helps, he did also, else he would not have mentioned it, if you don’t then that’s cool. it’s pretty far off topic for this post.
